Pollen Description

Shape, Size and Aperture

pollen unit: monad,  dispersal unit and peculiarities: monad,  size (pollen unit): small (10-25 µm),  size of hydrated pollen (LM): -,  shortest polar axis in equatorial view (LM): -,  longest polar axis in equatorial view (LM): -,  shortest diameter in equatorial or polar view (LM): -,  longest diameter in equatorial or polar view (LM): -,  pollen class: colpate,  polarity: isopolar,  P/E-ratio: -,  shape: spheroidal,  outline in polar view: circular,  dominant orientation (LM): -,  P/E-ratio (dry pollen): prolate,  shape (dry pollen): -,  outline in polar view (dry pollen): elliptic,  infoldings (dry pollen): aperture(s) sunken,  aperture number: 3,  aperture type: colpus,  aperture condition: colpate, tricolpate,  aperture peculiarities: -

Ornamentation and Structure

LM  ornamentation LM: -,  nexine: -,  sexine: -,  SEM  ornamentation SEM: microreticulate, reticulate, bireticulate,  suprasculpture SEM: -,  TEM  tectum: -,  infratectum: -,  foot layer: -,  endexine: -,  intine: -,  wall peculiarities: -,  supratectal element: -

Miscellaneous

pollen coatings: -,  reserves in cytoplasm: -,  cell number: -,  Ubisch bodies: -

Annotations: hydrated pollen approximately spheroidal to oblate, colpi arranged in angles of about 110/110/140 degrees, dry pollen therefore "flat"
